Almost got it working. Note, there is a typo in the document, last item references the dll file in "d:\" drive rather than the c:\ found previously. I'm receiving an error as follows right now:An error occurred during client rendering.An error has occurred during report processing. (rsProcessingAborted)This data source is configured to use Windows integrated security. Windows integrated security is either disabled for this report server or your report server is using Trusted Account mode. (rsWindowsIntegratedSecurityDisabled)

Am I supposed to be creating a limited user account and assigning to the data source in report manager rather than "windows integrated security" or is there a way to still use this?

We have followed the information here exactly as well as from THIS link (more or less the same information) and cannot get this to work on 2008 R2. I think R2 might be the kicker here as we get nothing but errors when trying this process.

Worked perfectly for me ,but got the following error when trying to run/view a Report

An internal error occurred on the report server. See the error log for more details. (rsInternalError)Could not load file or assembly 'Microsoft.ReportingServices.ProcessingObjectModel, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. Access is denied

It works Great.tnxbut let me add this stupid point that maybe helpful(I was hanged there)u have to rename second file and change format file from .txt to .dll and all of structures are completely enoughTnx again maan

I realise you posted this some time ago and I got this all running just fine on my Dev server running SQL Server 2008 standard edition, but it certainly doesn't like it on my Live server SQL Server 2008 R2 web edition.

Is there the possibility that the difference in versions is the problem here?
